CAR-ROOF.

SPECIFICATION forming part of Letters Patent No. 590,272, datedSeptember 21, 1897.

Application filed April 3, 1896- To all whom it may concern:

Be it known that I, JAMES J. MCCARTHY, a citizen of the United Statesresiding in Austin, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Car-Roofs, of which thefollowing is a specification, reference being had to the accompanyingdrawings, in which Figure 1 is a partial plan view, part of the roofbeing removed. Fig. 2 is a partial vertical cross-section. Fig. 3 is anenlarged detail, being a partial vertical cross-section. Fig. 4 is apartial longitudinal vertical section on line 4 4 of Fig. 3. Fig. 5 is asimilar view showing a modification.

My invention relates to car-roofs, and has for its object to provide animproved construction whereby leakage will be effectually prevented andwhereby danger from fire will be reduced to the minimum; also, toimprove the construction of car-roofs in general.

I accomplish the objects of my invention as hereinafter specified and asillustrated in the drawings.

That which I regard as new will be set forth in the claims.

In the drawings, 6 indicates the sides of the car; 7, the roof proper;8, the foot-boards; 9 10, vertically-arranged strips at the eaves of thecar and arranged a short distance from the sides of the car, as shown inFigs. 2 and 3.

11 indicates the ridge-pole.

12 indicates the rafters, which, as shown in Fig. 4, may be of somewhatinverted-T form,

or, as shown in Fig. 5, may be reversed, as indicated at 13.

In the form of construct-ion shown in Fig. 4 gutters 14 are provided ateach side of the central portion of the rafter, which forms a rib 15 andis secured by means of an intermediate block 16 to longitudinal beams17-, upon which the roof proper is secured.

In the form shown in Fig. 5 the rafter is secured directly to the beams17 and is provided at its under side with a rib 18, between which andthe usual longitudinal supporting-joists 19 corrugated metallicroofing-plates 20 are secured. 7

As best shown in Fig. 4, the edges of the roofing-plates 2O abut againstthe sides of the rafter, and said plates are secured in place Serial No.586,132. (No model.)

by an auxiliary plate 21, the edges of which are corrugated to fit thecorrugations in the plate 20, the intermediate portion of said plate 21being fiat and being secured between the rafter and the block 16, aspike 22 serving to hold all the parts together. The auxiliary plates 21project at each side of the supporting devices over and rest upon theroofingplates 20. This forms a loose connection between theroofing-plates and the plates 21. The arrangement of the intermediateplates over the roofing-plates serves to effectually prevent leakage,and also by making the barrier between the roof and the interior of thecar more complete affords a better safeguard against fire. The upperends of the roofingplates 20 extend up into the ridge-pole 11, as shownin Fig. 3. The lower ends of the roofing-plates terminate at the sidesof the car and discharge water into the space between the side of thecar and the strips 9 10.

The roofing-plates are preventedfrom slipping out of place by a seriesof stop-blocks 23 secured opposite the lower ends of said plates, asshown in Fig. 1. By this construction when it is desired to remove theroofingplates all that it is necessary to do is to re:

move the stop-blocks 23, as the plates, arenot nailed in position. Thisis especially advantageous, as it permits the plates to adjustthemselves to the shifting or racking of the car and also permits of theready removal of the plates for reuse in case of wreck. Furthermore, bythe use of the auxiliary plates 21 a complete barrier of. metal isprovided, which is an effectual safeguard from damage by fire. are aneflicient protection against leakage. Should any water leak between theplates 20 and 21, it will be caught and carried to the edge of the carby the gutters 14 in the rat ters. In this respect the construction ofrafters shown in Fig. 4 is that which I prefer.

I have described the construction 'of my improved car-roof in detail,but Ido not wish to be limited to such details of construction, as manymodifications may be made without departing from the spirit of myinvention.

That which I claim as my invention, and desire to secure by LettersPatent, is

1. In a roof, the combination with support- Such auxiliary plates also-ICO ing devices, and roofing-plates at each side thereof, ofintermediate plates connected to said supporting devices and projectingat each side thereof, and extending parallel with and fitting closelyupon the roofing-plates, forming practically a continuation of theroofingplates, substantially as described.

2. In a roof, the combination with rafters, and corrugatedroofing-plates at each side thereof, of intermediate corrugated platesconnected to the rafters and projecting at each side thereof, andextending parallel with and fitting closely upon the roofing-plates,forming practically a continuation of the roofingplates, substantiallyas described.
